Computer Simulation of Regional Evapotranspiration by Integrating Landscape Biophysical Attributes with Satellite Data

摘要: Evapotranspiration (ET) is an important link between the land-surface energy budget and hydrologic budget. The partitioning of incoming into sensible or latent heat substantially influences meteorology from local to global scales. components hydrologie that control ET are fairly well understood at scales (Shuttleworth, 1988). Measurement methods models exist describe adequately canopy interception, snowpack dynamics, soil water flux, itself when treated as “point” processes. Even biological ET, primarily manifested through leaf stomatal closure, now reasonably well, generalized treatment environmental functions available (Jarvis McNaughton, 1986). However, challenge enlarge our perspective GCM cell size, macrohydrology termed by Shuttleworth (1988), which necessitates a new consideration parameterization large areas (Eagleson,
